Wind-driven rain is the first thing the surveyor weighs up. Hampshire has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

On compliance, if cavity wall insulation follows in Farnborough, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Why debris matters

A clean cavity lets water that gets through the outer leaf drain away. Debris piled at the base or caught on ties makes a bridge for that water. It is a common cause of damp low on walls and around ties, with or without insulation.
